Monaco is a tiny but glamorous principality on the French Riviera known for its opulent lifestyle, luxurious casinos, and picturesque Mediterranean coastline. It attracts tourists with its world-class events such as the Monaco Grand Prix and the Monte Carlo Casino, as well as its rich cultural heritage, including the Prince's Palace and the Oceanographic Museum. Monaco's unique blend of wealth, natural beauty, and entertainment make it a magnet for tourists seeking a taste of luxury and glamour in a compact and stunning destination. I embarked on a day trip to Monaco from Nice by train.
